Android Skills MCP
Android Skills MCP wraps Google's [`android/skills`](https://github.com/android/skills) library so any AI coding assistant can use it without copy and paste. The repository ships two tools that share a common parser and a bundled snapshot of the upstream skills, so both work offline through `npx`.
You get an MCP server that exposes the skill library to any MCP capable client, and a packager CLI that converts each `SKILL.md` into the native rules format of every major AI coding assistant.
Full documentation lives at **[skydoves.github.io/android-skills-mcp](https://skydoves.github.io/android-skills-mcp/)**.
## Packages
This is a pnpm workspace with three packages:
- **[`android-skills-mcp`](packages/mcp)** is an MCP server. It speaks stdio, ships three tools (`list_skills`, `search_skills`, `get_skill`), and exposes every skill as a `skill://` resource. Any MCP client (Claude Code, Cursor, Codex CLI, Windsurf) can discover and pull the right skill on demand.
- **[`android-skills-pack`](packages/pack)** is a CLI. It converts the upstream `SKILL.md` files into seven native rules formats (Claude Code, Cursor, GitHub Copilot, Gemini Code Assist, JetBrains Junie, Continue.dev, Aider) and writes them into your project.
- **[`@android-skills/core`](packages/core)** is the shared library used by both. It parses `SKILL.md` frontmatter with `gray-matter`, validates against the [agentskills.io](https://agentskills.io/specification) spec via `zod`, and builds a BM25 index with `minisearch`.
## How to install the MCP server
You need this once per machine. Every project you open afterwards can use the skills.
### Claude Code
```bash
claude mcp add android-skills -- npx -y android-skills-mcp
```
### Cursor
Add an entry to `.cursor/mcp.json`:
```json
{
"mcpServers": {
"android-skills": {
"command": "npx",
"args": ["-y", "android-skills-mcp"]
}
}
}
```
### Other MCP clients
Anywhere you can register an MCP server with a stdio command, run:
```
npx -y android-skills-mcp
```
The bundled snapshot loads in under 200 ms, so the cost of spawning the server per session is negligible.
## How to install skills as files
If you prefer rules files committed to your repository over an MCP server, the packager CLI writes them directly. You can pick a single target or `all`:
```bash
npx android-skills-pack install --target cursor
npx android-skills-pack install --target claude-code
npx android-skills-pack install --target copilot
npx android-skills-pack install --target all
```
You can also filter to a specific skill:
```bash
npx android-skills-pack install --target cursor --skill edge-to-edge
npx android-skills-pack install --target claude-code --skill edge-to-edge,r8-analyzer
```
The full list of supported targets:
| Target | Output | Notes |
|---|---|---|
| `claude-code` | `.claude/skills//SKILL.md` | Near 1:1 copy with references kept as separate files. |
| `cursor` | `.cursor/rules/.mdc` | `description` plus `alwaysApply: false` frontmatter; references inlined. |
| `copilot` | `.github/instructions/.instructions.md` | `applyTo: "**"` frontmatter. |
| `gemini` | `.gemini/styleguide.md` | Single concatenated file with `## ` sections. |
| `junie` | `.junie/skills//SKILL.md` | JetBrains Junie supports the agentskills.io spec natively. |
| `continue` | `.continue/rules/.md` | `name`, `description`, `alwaysApply` frontmatter. |
| `aider` | `CONVENTIONS.md` (repo root) | Single file. Add `read: CONVENTIONS.md` to `.aider.conf.yml`. |
## Repository layout
```
android-mcp/
├── packages/
│ ├── core/ @android-skills/core parser, schema, search index
│ ├── mcp/ android-skills-mcp MCP server (stdio)
│ └── pack/ android-skills-pack packager CLI
├── scripts/ sync-skills.mjs, build-skills-index.mjs
└── skills/ upstream android/skills clone (gitignored)
```
The `skills/` directory is a plain clone of `android/skills` and is gitignored. You only need it for development. Both published packages bundle a parsed snapshot of the skills inside `dist/skills.json`, so end users never need the upstream repository.
## Development
Clone, install, and run the test suite:
```bash
git clone https://github.com/skydoves/android-skills-mcp.git
cd android-mcp
pnpm install
pnpm sync:skills
pnpm build
pnpm test
```
The build runs in topological order: `core` first, then `mcp` and `pack` in parallel. Each package has its own `vitest` suite. The full test count is 64 across the three packages.
You can smoke test the MCP server over stdio without any client:
```bash
printf '%s\n' \
'{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"smoke","version":"0"}}}' \
'{"jsonrpc":"2.0","method":"notifications/initialized"}' \
'{"jsonrpc":"2.0","id":2,"method":"tools/list"}' \
| node packages/mcp/dist/bin.js
```
